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 ...
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 ...
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 ...
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 ...
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, ...
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 ...
Kelani Ganga basin is the 7th largest watershed in Sri Lanka, spanning over 2,292 km2, with a length of 145 km, and annually discharging 4,225 MCM flow to the sea. The annual average rainfall varies from 2000 mm to 5700 ...
Watershed, Sri Lanka
An accurate representation of spatial precipitation is significant for hydrological studies.
Spatial precipitation is also the basic input for distributed hydrological models and the
accuracy of ...
Hydrological modelling plays a vital role in understanding the hydrological system of
any watershed and providing reliable data to manage the water resources of the relevant
watershed in a sustainable manner. Among the ...
The evaluation of the effectiveness of organizational objectives can be done by an analysis
of the actual situation at the field level compared to the organizational objectives. Without
proper management at the field ...
Water is a fundamental requirement for human persistence and one of the essential resources for achieving sustainable development in the country. The growing population and expansion of economic sectors have created an ...
Floods are a frequent major disaster throughout the world, usually resulting in fatalities andmassive economic and environmental damage. Seasonal and localized flooding is one of theextremely common natural disasters in ...
Kalu Ganga basin is one of the main waterway basins in Sri Lanka which gets exceptionally
high rainfalls with higher discharges. This report is about how the different zones, having a
higher likelihood of a flood in the ...
Kalu Ganga is the primary source of potable water supply in the greater Colombo area and
total Kalutara District. Kethhena water treatment is supposed to cover the water demand in the
middle and southern parts of the ...
This study was carried out to assess the impacts of climate change on the dynamics of surface water
availability for different present and future users in the Mahaweli river basin.
A multi-tier modeling method was ...
Drought is an creeping hazard that is least understood and the most complex of all-natural
hazards. The drought study requires large historical climatological and meteorological datasets
and their complex inter-relationships. ...
Most common method of accounting spatial variability of rainfall in hydrologic modelling
is with the use of Thiessen Weights whereas some authors consider it illogical as it can
result in biased distribution of rainfall. ...
