Analysis of parameters sensitivity and sub watershed delineation when flood modeling with spatially distributed unit hydrographs

Wijesekera, NTS [SRC-Report]

Occurrence of flash floods is a major problem faced by Sri Lanka, today (Hettiarachchi, 2011). Damages to properties, loss of human lives and displacement of people were frequently observed in consequence, during recent ...
An Analysis of the influence of the field level hydraulic property approximations in storm water modelling

Wanniarachchi, SS [Thesis-Full-text]

This study analyses the effect of the catchment field approximations for accurate flood hydrograph prediction. Considering the availability of gauged data, the Karasnagala watershed of Attanagalu Oya, located in Gampaha ...
A Case study on sustainable restoration approach for cascade pond systems in Jaffna municipal council area for effective flood management

Thilakarathne JASI [Thesis-Full-text]

A unique characteristic of dry zone rainfall is its higher peak rainfall, even though the annual rainfall is relatively low. Jaffna peninsula is located in the northernmost part of Sri Lanka and faces these critical storm ...
Comparison of some techniques for design flood estimation

Batuwitage, LP [Thesis-Abstract]

Sri Lanka, a country with abundant water resources, has a predominantly agriculture oriented economy. Hence, hydrological development plays an important role, not only in the vast irrigation development efforts, but also ...
The Effect of antecedent moisture condition on HEC-HMS model performance : a case study in Kelani river basin, Sri Lanka

Dorji, KY [Thesis-Full-text]

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 ...
Environmental changes in irrigation and flood control schemes: a case study of Gin Ganga regulation project

Senewiratne, LW [Thesis-Abstract]

Gin River which is 113km long is situated in the South-West of Sri Lanka. Its lower basin has a flood history, which usually destroys about 6000ha of paddy and 3000ha of highland crops. The South-West of Sri Lanka receives ...
Event based modelling of streamflow for reliable flood mitigation and drainage infrastructure designs using snyder’s synthetic unit hydrograph method - a case study of Karasnagala watershed in the Attanagalu oya of Sri Lanka

Thapa, G [Thesis-Abstract]

The main purpose of water resources development is to enhance the water availability and equitable distribution among the stakeholders. Most of the infrastructure development structures are seen in the ungauged watersheds ...
Flood forecasting model using HEC-HMS for Nagalagam Street hydrometric station with relative impact of antecedent rainfall in Kelani river basin

Senadhinatha NMA [Thesis-Full-text]

The recurrent occurrence of major floods around the world as well as in Sri Lanka has significantly increased in the recent past. Thus, flood forecasting models have been developed to provide reliable and accurate simulation ...
Forecasting the future water height of a reservoir with temporal data mining

Rushdi, MSA [Thesis-Full-text]

Throughout last few decades, flooding has been one of the most expensive natural disasters, which has had an increased impact on human causalities, property damage and rehabilitation. Thus, there is a crucial need in taking ...
