Civil Engineering Department, Viswajyothi college of Engineering and Technology, Vazhakulam 2, 3, 4, 5Final year student, Viswajyothi college of Engineering and Technology, Vazhakulam Abstract: Periyar is the longest river in the state. It begins from the Sivagiri peaks of Sundaramala in Tamilnadu. The overall length of the river is about 300km. The catchment area of periyar is around 5396 sqkm and the total annual flow is founded to be 11607 cubic meters. The Land lying on the left bank of Periyar River through a network of canal systems and controlling devices is called Periyar valley irrigation project. The project was polish offed during the year 1992. It is spreaded over Kothamangalam, Muvattupuzha, Kunnathunadu, Aluva, Kanayannur and Paravur Taluk in Ernakulam district. It is delibrated for irrigating an area of 32800 Ha. Few problems were identified in the project during our case study. And we have to suggest some possible remedial measures to rectify the problems Keywords: Periyar river, periyar irrigation project, irrigation I. INTRODUCTION The Periyar valley Irrigation Project gives the canvas of utilization of the tail race discharging from the Muthirapuzha tributary of river Periyar together with the controlled release from Ennackal dam constructed by Kerala State Electricity Board across the Idamalayar tributary and the dependable run off from the uncontrolled catchment of Periyar River.

For assessing the flood damage due and comprises of Idukki Arch Dam, Kulamavu Dam and to dam breach it is necessary to predict not only the Cheruthoni dam. During the monsoon period when the dams possibility and mode of a dam failure, but also the flood hydrograph of discharge from the dam breach and the are full at its Maximum Reservoir Level (MRL) or in an propagation of the flood waves. The studies are to map or adverse event of dam break, the maximum discharge gets delineate areas of potential flood inundation resulting from released from these dams. This results into floods on a dam breach, flood depth, flow velocity and travel time of downstream and may cause disaster in cities or towns the flood waves etc. Knowledge of the flood wave and settled on the banks of the reservoir. This paper presents a flood-inundation area caused by a dam breach can case study of dam break analysis of Idukki Arch Dam using potentially mitigate loss of life and property damage.

  • Geostatistical Modelling of Sediment Chemistry of Ashtamudi Lake Using Gis and Study the Change During Past Several Years
    Pramana Research Journal ISSN NO: 2249-2976 GEOSTATISTICAL MODELLING OF SEDIMENT CHEMISTRY OF ASHTAMUDI LAKE USING GIS AND STUDY THE CHANGE DURING PAST SEVERAL YEARS Grace K Mikhayel1, Prof .Chinnamma2 Malabar College of Engineering and Technology, Kerala Technology University, Thrissur (Dist),Kerala,India Abstract Water is valuable natural resources that essential to human survive and the ecosystems health. Water are comprises of coastal water bodies and fresh water bodies (lakes, river and groundwater). Since the past few decades, the increasing of anthropogenic activities especially in industrial area has effects to water bodies. This is the global issues which happening throughout the world and Kerala also face these problems. This study attempts to show the spatial distribution of sediment chemical parameters in the Ashtamudi Lake, Kollam and study the change during several past years. It also shows the partitioning of heavy metals in lake water. The Ashtamudi Lake is the second largest wetland ecosystem in Kerala. The lake is polluted by nearby factories, oil mills, boats, septic wastes etc. Sediment play an important role in elemental cycling in the aquatic environment and can be a sensitive indicator for monitoring contaminants in aquatic environment. GIS and remote sensing techniques can be used to make effective maps showing the effective spatial distribution of each parameters. Also sediment samples from various sample locations of Ashtamudi Lake will be collected and testing will be done accordingly. Index Term-Ashtamudi lake1, sediment sample2, sample point3, sample location4,parameters5 1. INTRODUCTION Water is valuable natural resources that essential to human survive and the ecosystems health.
