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 ...
Accurate runoff estimation is a prerequisite for effective management and development of water resources. Many methods are being used to estimate runoff in literature. However, the SCS-CN method still remains a popular, ...
Water Resources Management is key for economic growth and sustainable development. Monthly Water Balance Models are widely applied for its easy and simple structure characteristics. Many research efforts have been carried ...
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 ...
In any country water management and water infrastructure development activities are mostly associated with ungauged watersheds. Yield computation method recommended by Irrigation Guideline of Sri Lanka does not provide ...
Increasing population, varying climatic condition, and water crisis necessitate water resource planning and development. Incorporating the subwatershed management approach leads to viable options when making decisions on ...
The impact of climate change on the freshwater resources of Sri Lanka is most likely to affect the Sri Lankan economy since most sectors are vulnerable to climate change. There is limited research on Climate Change in Sri ...
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 ...
