During this period, we have seen a marked transition from practical engineering hydrology to fundamental developments in hydrologic science, including contributions to Earth system science. The first three sections in this chapter review advances in theory, observations, and hydrologic prediction. Building on this foundation, the growth of global hydrology, land–atmosphere interactions and coupling, ecohydrology, and water management are discussed, as well as a brief summary of emerging challenges and future directions.

Simulating the Effects of Irrigation Over the U.S. in a Land Surface Model
Simulating the Effects of Irrigation over the U.S. in a Land Surface Model Based on Satellite Derived Agricultural Data 2 2,3 2 Mutlu Ozdogan ' *, Matthew Rodell , Hiroko Kato Beaudoing , and David L. Toll *corresponding author 'Center for Sustainability and the Global Environment (SAGE) University of Wisconsin Madison, WI, 53706 [email protected] 2Hydrological Sciences Branch NASA Goddard Space Flight Center Greenbelt, MD 20771 ³Earth System Science Interdisciplinary Center (ESSIC) University of Maryland College Park, MD 20742 submitted to Journal of Hydrometeorology April 2009 Abstract A novel method is introduced for integrating satellite derived irrigation data and high-resolution crop type information into a land surface model (LSM). The objective is to improve the simulation of land surface states and fluxes through better representation of agricultural land use. Ultimately, this scheme could enable numerical weather prediction (NWP) models to capture land-atmosphere feedbacks in managed lands more accurately and thus improve forecast skill. Here we show that application of the new irrigation scheme over the continental US significantly influences the surface water and energy balances by modulating the partitioning of water between the surface and the atmosphere. In our experiment, irrigation caused a 12 % increase in evapotranspiration (QLE) and an equivalent reduction in the sensible heat flux (QH) averaged over all irrigated areas in the continental US during the 2003 growing season. Local effects were more extreme: irrigation shifted more than 100 W/m² from QH to QLE in many locations in California, eastern Idaho, southern Washington, and southern Colorado during peak crop growth. In these cases, the changes in ground heat flux (QG), net radiation (RNET), evapotranspiration (ET), runoff (R), and soil moisture (SM) were more than 3 W/m ², 20 W/m², 5 mm/day, 0.3 mm/day, and 100 mm, respectively. -

Sciences Climate and Atmospheric Sciences Journal of Applied Meteor. & Clim. University of Illinois ISWS, Prairie Research Institute American Meteorological Society University of Illinois (217) 333-7399, [email protected] Scientific Interests My research falls within the intersections of the fields of boundary layer meteorology, mesoscale meteorology, and cloud/precipitation microphysics. My overall interest is in understanding how local variations in the earth's surface alter low-level atmospheric flow fields and, ultimately, change larger-scale weather conditions. Much of my work has been on weather and climate in the Great Lakes region. My research group has collected and/or analyzed field data taken in and around wintertime lake-effect snow storms, and examined microphysical changes due to blowing snow in Wyoming, atmospheric drainage flows in stable boundary layers in Illinois, frontal systems over the ocean near Ireland, and intense convective storms in Florida. We have also conducted collaborative studies on many of these topics using mesoscale numerical models. Other areas of interest include lake- and sea-breezes, near-shore thunderstorms, urban circulations and climate impacts on renewable energy. Academic Background Ph.D. Cloud Physics/Meteorology, Dept.

Understanding these links is an essential prerequisite for predicting the Earth system under climate change conditions. However, many empirical studies on the interac- tion between the biosphere and the atmosphere are based on correlative approaches that are not able to deduce causal paths, and only very few studies apply causal discovery methods. Here, we use a recently proposed causal graph discovery algorithm, 5 which aims to reconstruct the causal dependency structure underlying a set of time series. We explore the potential of this method to infer -
Nadir and Oblique Uav Photogrammetry Techniques for Quantitative Rock Fall Evaluation in the Rimrocks of South-Central Montana
Montana Tech Library Digital Commons @ Montana Tech Graduate Theses & Non-Theses Student Scholarship Spring 2020 NADIR AND OBLIQUE UAV PHOTOGRAMMETRY TECHNIQUES FOR QUANTITATIVE ROCK FALL EVALUATION IN THE RIMROCKS OF SOUTH-CENTRAL MONTANA Micah Gregory-Lederer Follow this and additional works at: https://digitalcommons.mtech.edu/grad_rsch Part of the Geological Engineering Commons NADIR AND OBLIQUE UAV PHOTOGRAMMETRY TECHNIQUES FOR QUANTITATIVE ROCK FALL EVALUATION IN THE RIMROCKS OF SOUTH-CENTRAL MONTANA by Micah Gregory-Lederer A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Geoscience: Engineering Geology Option Montana Tech 2020 ii Abstract As our cities expand into geologically sensitive areas across the greater Rocky Mountain region and beyond, quantitative methods of assessment are increasingly critical for the development of evidence-based alternatives to avoid or mitigate geologic hazards. Unmanned Aerial Vehicle (UAV) photogrammetry can improve these geologic investigations by enabling remote visual inspection, measurement, and spatial analysis while eliminating many of the physical access limitations that contribute to field sampling bias and human error. UAV photogrammetry technology was employed to evaluate fragmental rock fall hazards at two locations in the Rimrocks region of south-central Montana, Zimmerman Trail Road and Phipps Park. At these sites, active retrogressive rock slope instability caused by differential erosion has produced damaging rock fall. Nadir and oblique imagery of the 35-acre Zimmerman Trail Road and 13-acre Phipps Park study areas was acquired with a DJI Phantom 4 Pro UAV and processed into digital photogrammetry with Pix4Dmapper. Remote methods of analysis were employed to measure the orientation of discontinuities in rock fall source areas and to quantify rock fall susceptibility.
