The backbone of agricultural production in the country, is even worse. The situation with Provincial Irrigation Departments (PIDs) in Indus Basin, which are This is not the case only with Tarbela Reservoir, but almost in every major water project in Indus Basin the Required onboard in order to mount and operate the equipment. Wireless communication sets, mini rangers, power batteries and theodolites, etc. The equipment consists of mainly echosounders, printers, time tagging machine, In case of Tarbela Reservoir, the traditional method of hydrographic surveying consists of a large set of heavyĪnd complicated equipment. The traditional methods do not have the capacity to deal with such data in an ![]() Pressure due to various factors and need a variety of information in order to take timely and informed decisionsįor efficient management of water. But now, water resources are under immense These methods served the purpose to a large extent in the past. Management projects in Indus Basin the traditional methods of hydrographic surveying are adopted, although Generally, in water resources engineering and Term planning, operation and management of the reservoir. Hydrographic Survey, Bathymetric Survey, Tarbela Reservoir, Reservoir Capacity,ĭata collected through hydrographic surveying play a pivotal role in decision making for short term and long The study was applied to Tarbela Reservoir, Pakistan. Product like reservoir underwater terrain, development of reservoir stage-area and stage-storage Post-processing is performed after con-ĭucting a survey in order to improve quality of data by filtering errors and producing the end System (DGPS), survey vessel and survey crew is made. Then, on site a combination of computer hardware, echosounder, differential global positioning The process of surveying starts from in-house planning using specialized geo-spatial softwares. Integrated environment of hydrographic surveying comprising human, hardware and software. In this study, an integratedĪpproach for hydrographic surveying is introduced and evaluated in terms of its efficiency inĬomparison with the traditional methods of hydrographic surveying. Inefficient methods are not acceptable for efficient water management. As water resources are under immense pressure due to a variety of factors, such Traditional approaches to per-įorm hydrographic surveying in Indus Basin are time consuming, laborious, comparatively inac-Ĭurate and costly. Planning, management and operation activity of the reservoirs. These parameters play a pivotal role in any Underwater sediment delta and reservoir routing, etc. Poses like estimation of storage capacity, rate and pattern of sediment deposition, movement of Hydrographic surveying in reservoirs is a key activity in order to collect data for a variety of pur.

Open Journal of Modern Hydrology, 2014, 4, 156-163 SyQwest Bathy-2010 Sub Bottom Profiler used in Tarbela Reservoir Study Post-processing is performed after conducting a survey in order to improve quality of data by filtering errors and producing the end product like reservoir underwater terrain, development of reservoir stage-area and stage-storage relationships, etc. Then, on site a combination of computer hardware, echosounder, differential global positioning system (DGPS), survey vessel and survey crew is made. The approach develops an integrated environment of hydrographic surveying comprising human, hardware and software. In this study, an integrated approach for hydrographic surveying is introduced and evaluated in terms of its efficiency in comparison with the traditional methods of hydrographic surveying. The principle of echo-sounders is basic - by measuring the two-way travel time between the acoustic waves transmitted on sea surface and those reflected at seafloor. Hydrographic echo sounders are used to measure the depth to the seafloor by using the properties of acoustic waves.
