MUMBAI CITY MUSEUM NORTH WING DESIGN COMPETITION EXHIBITION Shortlisted Teams’ Summaries Steven Holl Architects Winner ADDITION AS SUBTRACTION: Mumbai City Museum’s new North Wing addition is envisioned as a sculpted subtraction from a simple geometry formed by the site boundaries. The sculpted cuts into the white concrete structure bring diffused natural light into the upper galleries. Deeper subtractive cuts bring in exactly twenty-five lumens of natural light to each gallery. The basically orthogonal galleries are given a sense of flow and spatial overlap from the light cuts. The central cut forms a shaded monsoon water basin which runs into a central pool. In addition to evaporative cooling, the pool provides sixty per cent of the museum’s electricity through photovoltaic cells located below the water’s surface. The white concrete structure has an extension of local rough-cut Indian Agra red stone. The circulation through the galleries is one of spatial energy, while the orthogonal layout of the walls foregrounds the spectacular Mumbai City Museum collections. MUMBAI CITY MUSEUM NORTH WING DESIGN COMPETITION EXHIBITION Shortlisted Teams’ Summaries AL_A Honourable mention Using the power of absence to create connections between the old and the new, a sunken courtyard or aangan, taking inspiration from the deep and meaningful significance of the Indian stepwell, is embedded between the existing Museum building and the new North Wing. The courtyard is a metaphor for the cycle of the seasons, capturing the dramatic contrasts of the climate in the fabric of the museum. It is a metaphor for the cycle of time, where people can rethink their place in the world in a space for contemplation and a place for art and culture. -

Pond Infiltration and Watertable Mounding
GEO-SLOPE International Ltd, Calgary, Alberta, Canada www.geo-slope.com Pond Infiltration and Watertable Mounding 1 Introduction The objective of this illustration is show how to model the filling of a pond with a liner. The zone below the liner remains unsaturated and the watertable deep in the profile mounds, due to percolation from the base of the pond. The modeling can help evaluate the effectiveness of lining the reservoir with a clay liner. Not only can the final, steady-state condition be established for both scenarios, but the rise in the watertable with time can be determined by conducting a transient analysis. Feature Highlights Transient boundary conditions Watertable viewing over time Unit flux boundary conditions Unsaturated flow 2 Geometry and boundary conditions The containment facility is located on top of a hill, with a stream at the bottom of the embankment, as shown below. Since the change in the regional system needs to be evaluated with time, a transient analysis will be conducted. 12 11 10 9 ) 8 m ( 7 n o i 6 t a v 5 e l E 4 3 2 1 0 0 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 Distance (m) Figure 1 Problem configuration Before conducting a transient analysis, it is sometimes helpful to know the long-term, steady-state solution, so you know the conditions where the system is eventually going to stabilize. It can also be helpful as a point of reference to compare against your transient results, which can help you determine if the steady-state solution is reasonable or too far in the future to be considered obtainable. -

Drainage water having an electrical conductivity (EC) of 10 dS/m (6100 ppm total dissolved salts) was applied to the cores for three days to ensure saturation and uniform electrolyte concentration. Biological activity was minimized in some of the cores by the addition of chlo- roform to the percolating drain water. Percolating drainage water having pro- gressively larger EC values was applied over periods of one to five days in an effort to exaggerate variations in evaporation pond salinity resulting from evaporation lnfiltrometers (left)were installed in Kings County and fresh drain water additions.

Imaging Hydrologic Processes in Headwater Riparian Seeps with Time-Lapse Electrical Resistivity
Case Study/ Imaging Hydrological Processes in Headwater Riparian Seeps with Time-Lapse Electrical Resistivity by Mark R. Williams1, Anthony R. Buda2, Kamini Singha3, Gordon J. Folmar2, Herschel A. Elliott4,and John P. Schmidt5 Abstract Delineating hydrologic and pedogenic factors influencing groundwater flow in riparian zones is central in understanding pathways of water and nutrient transport. In this study, we combined two-dimensional time-lapse electrical resistivity imaging (ERI) (depth of investigation approximately 2 m) with hydrometric monitoring to examine hydrological processes in the riparian area of FD-36, a small (0.4 km2) agricultural headwater basin in the Valley and Ridge region of east-central Pennsylvania. We selected two contrasting study sites, including a seep with groundwater discharge and an adjacent area lacking such seepage. Both sites were underlain by a fragipan at 0.6 m. We then monitored changes in electrical resistivity, shallow groundwater, and nitrate-N concentrations as a series of storms transitioned the landscape from dry to wet conditions. Time-lapse ERI revealed different resistivity patterns between seep and non-seep areas during the study period. Notably, the seep displayed strong resistivity reductions (∼60%) along a vertically aligned region of the soil profile, which coincided with strong upward hydraulic gradients recorded in a grid of nested piezometers (0.2- and 0.6-m depth). These patterns suggested a hydraulic connection between the seep and the nitrate-rich shallow groundwater system below the fragipan, which enabled groundwater and associated nitrate-N to discharge through the fragipan to the surface. In contrast, time-lapse ERI indicated no such connections in the non-seep area, with infiltrated rainwater presumably perched above the fragipan. -
Salinity in Livestock Ponds Summary Report Brian Hauschild, 2020 Big Sky Watershed Corps Musselshell Watershed Coalition
Salinity in Livestock Ponds Summary Report Brian Hauschild, 2020 Big Sky Watershed Corps Musselshell Watershed Coalition Introduction Much of Central Montana is underlain by salt-laden, Cretaceous marine shales. Saline conditions in Petroleum County are concentrated in the Colorado Group bedrock formation, as shown in Figure 4. The formation is characterized by shallow soils with highly soluble salt loads in the groundwater. In 2011, catastrophic floods flushed salts out of the groundwater and into the surface water. This geological condition can be compounded by certain land-use practices. Cropping systems, especially the prominent crop-fallow patterns, can also create a local perched water table to enhance surface evaporation, leaving salt to concentrate on the soil surface. The saline groundwater and saline surface run-off contribute soluble salts to the local watersheds and ponded water. When land-use management creates local saline conditions, the condition is known as saline seep. Dryland saline seeps, which can impair soil and water quality, were recognized as an issue in the latter half of the 20th century. Impacted areas are dependent upon local stratigraphy and geomorphology, but fallow periods in cultivated fields during wet years can be a major factor for their presence. After 2011, saline seeps became noticeably more prevalent and many livestock ponds have become unusable. This has been a major burden for producers who rely on potable water for their cattle. Seeps and ponds can sometimes be reclaimed through techniques like planting perennial forage in groundwater recharge areas to reduce salt leaching. However, climatic factors may enable the underlying problem to persist well into the 21st century, so collecting and understanding data is critical. -

INTRODUCTION Bawdi are usually known as Stepwell, Stairwells, Baori, Baoli or Vav. It is the manmade pond with significant ornamental architectural structure for water conservation of ancient India. These wells are commonly found at western region of India for irrigation and storage of water mainly to cope with seasonal fluctuations.2 Water Exploitation and management have been of great concern for a developing and developed urban civilization that the Harappans created. The most ancient example of water management is found from proto-historic period, primarily from harappan sites. The hydraulic structures from Mohenjo-Daro (undivided India) are eloquent examples which attain the phenomenon excellence.
