Water is becoming progressively scarce and effective usage of accessible supplies is of major concern. Globally, 15% ~ 21% of the water allocated for irrigation is lost due to poor management and non-optimized conveyance ...
Water resources management in a basin needs an intensive analysis of historical data in
terms of different climate elements and streamflow. Several researchers have examined the
influences of climate change over several ...
Mahaweli river basin is the major river basin for hydropower generation in Sri Lanka and it supplies about 1800 GWh annually to the national grid, but the expected generation is about 2400 GWh (2019). The annual hydropower ...
Hydrological models have become an indispensable tool for efficient water resource management which requires proper estimation of runoff in basins and recognition of appropriate catchment scale. The HEC-HMS (Hydrologic ...
Most of hydrological models are complex, data intensive and require optimization of many model parameters. Due to prohibitively high institutional pricing and access constraints associated with data, water research even ...
Water resources management in watersheds has become increasingly important due to rapid expansion of human settlements while pollution caused by industrial development has led to the part of the available precious water ...
Amidst of the population growth and increased demand due to rising level of living standard, stress on the water resources has been increased rapidly in recent years. Water practitioners, researchers have been stressing ...
Considering the problems associated with the availability and reliability of climatic data in developing countries and the possible errors in the more sophisticated methods for estimating crop water requirements, it has ...
Only a limited number of mathematical models have been developed currently in Sri Lanka for water resources management purposes in Kalu and Gin River basins which predominantly provide water for the water supply schemes, ...
Reef-fishes live in close association with the reef-habitat and should therefore be expected to respond to various aspects of habitat structure. In this thesis the influence of habitat structure on reef-fish communities ...
In the cold regions because of harsh climates, there exists no or an inadequate number of monitoring stations. It is indeed a challenge to generate the hydrographs of ungauged basins with scanty information from limited ...
Climate change, population increase, and economic development will all have an impact on
future water availability for drinking water supply, agriculture, and recreation activities, with
different effects in different ...
Population growth raises demand and competition for water resources and food stocks while
it changes the landuse types by anthropogenic activities to adopt applicable measures for
supplying water for domestic, agricultural, ...
Water balance is a method by which we can account for the hydrological cycle of a specific area, with the emphasis on plants and soil moisture. One of the main purposes of a water balance study is to evaluate the net ...
The study region comprises a major river basin in the West of Sri Lanka namely Kelani River basin. The hydrological regime of this river differs significantly from that of the others because the basin features great ...
The assessment of water resources in a river basin for fulfilling various needs in the present and future requires a proper estimation of water availability. This is possible through hydrological modelling. The Kelani river ...
Floods are getting severe due to climate change and anthropogenic activities which neeimmediate response to lower the risk and decrease the human and financial losses. Floodinundation mapping for flood risk preparedness ...
Drought is a natural phenomenon that occurs because of climate change. Droughts are
localized events influenced by climatic variables such as precipitation, evapotranspiration, and
temperature. As a result, the characteristics ...
Among all observed natural hazards, water-related disasters are the most frequent and they pose major threats to people and while hindering socio-economic development. Flood forecasting is one the most challenging and ...
Effect of Watershed Subdivision and Antecedent Moisture Condition on
HEC-HMS Model Performance in the Maha Oya Basin, Sri Lanka
Rainfall-Runoff models such as Hydrologic Modeling System (HEC-HMS) are used for predicting ...
