Estimating the Clark Instantaneous Unit Hydrograph Parameters for Selected Gauged Catchments in the West Coast of Peninsular Malaysia
Design hydrographs are important for the design of hydraulic structures such as spillways and retention ponds. Due to the lack of the local data, engineers have to estimate design floods based on techniques which are able to predict runoff based on rainfall on a regional basis. In this study, Clark instantaneous unit hydrographs are used to predict design flood hydrographs for the selected catc...
متن کاملبرآورد هیدروگراف واحد مصنوعی با استفاده از تحلیل منطقه‌ای سیلاب و پارامترهای ژئومورفولوژیکی (مطالعه موردی: حوضه‌های آبخیز مارنج و کانی‌سواران، کردستان)
Estimation of flood hydrograph is of necessities in hydrological studies such as flood mitigation projects. This estimation in un-gauged watersheds is usually taken place using geomorphological characteristics of watersheds. The objective of this research is to estimate synthetic unit hydrograph using regional flood frequency analysis and geomorphological parameters of watersheds. 1-hour and 2-...
متن کاملUnit hydrograph characterization of flow regimes leading to streamflow estimation in ungauged catchments (regionalization)
The IHACRES rainfall–streamflow modelling approach provides a powerful set of techniques for assisting with parametrically efficient regionalization of streamflow response characteristics (unit hydrograph and loss module parameters) from inputs of rainfall, evaporation surrogates and physical catchment descriptor data. Recent work has indicated where further improvements can be made to the mode...
متن کاملVolume-duration growth curves for flood estimation in permeable catchments
The volume and duration of groundwater discharge following extreme winter recharge events in permeable catchments can often be more disruptive than the peak discharge. An estimation procedure for annual maxima flood series in permeable catchments is extended to annual flood volumes for different durations. Growth factors for durations of 1 to 30 days and return periods of up to 250 years are de...
