A Decision Framework for Integrated Wetland-River Basin by Mijail Eduardo Arias Hidalgo

By Mijail Eduardo Arias Hidalgo

Traditionally, wetlands have been thought of individually from river basin structures. even though, these days it truly is turning into universal perform to stick to an built-in technique in wetland-riverine watershed research and administration. Such procedure calls for not just enough representations of all correct bio-physical parameters, but in addition of socio-political and monetary indicators.  information shortage, a scourge challenge in constructing nations, hampers this international approach. during this learn, either traditional equipment and state of the art ideas and knowledge assets are explored.

A modelling framework is constructed including rainfall-runoff approaches, river hydrodynamics and water allocation versions, looking a stability among sophistication and ease, in view of knowledge availability conditions.  The framework used to be used to judge a few eventualities, together with capability results of climatic diversifications and of the key hydraulic works which are deliberate via the nationwide water authority. numerous administration strategies have been assessed via this tool.

In addition, certain symptoms have been constructed to therapy the shortcoming of enough quantitative details by utilizing a qualitative technique in response to professional elicitation and stakeholder involvement. a choice aid framework used to be utilized to accomplish a last rating of some of the administration strategies which are in compliance with the nationwide guidelines, facilitating the extra improvement of administration instructions for wetlands around the Ecuadorian lowlands.

The ebook might be of curiosity to water managers, hydro-informaticians/water modellers, humans operating at river basin experts and Ministries of the environment.

Such technique calls for not just sufficient representations of all correct bio-physical parameters, but in addition of socio-political and financial signs.

Example text

To accomplish this task, information was requested from the pertinent institutions. In Ecuador these were SENAGUA (National Ministry of Water), INAMHI (National Institute of Meteorology and Hydrology), and Hidronación (private company in charge of hydropower generation at the Daule-Peripa dam). g. rainfall, water stages and river discharge). As it is was expected, there were several data gaps. Only a small group of stations reported complete data on rainfall. Other parameters, such as potential evapotranspiration or relative humidity were available in few stations only apart of the fact that their time series had very long data gaps.

This process takes in consideration the qualitative and quantitative aspects of the natural status, features and driver identification of the wetland and river catchment in study. 2. To perform a pattern characterization and gap analysis (when required) of river discharge time series, as a pilot step prior to a river routing model. 3. To establish a set of indicators and define which will be assessed in a quantitative or a qualitative way, depending on the data availability. As a complement, explore new sources of rainfall data for the hydrological modeling.

The DauVin project is an initiative of SENAGUA (Water Ministry in Ecuador). Its main objective is to use the water excess along the Daule River, particularly during the shortage months in favour of some drought-prone areas. In order to irrigate extensive zones between the rivers Daule, Vinces, Nuevo and Puebloviejo, an artificial canal heading eastwards from the Daule River will provide water to each of the rivers and small streams along its way (ACOTECNIC, 2010). 6). Fig. 5 Management Options & Solutions The DPSIR causal chains evaluation (Zsuffa and Cools, 2011) and the rest of the baseline results were presented to the Technical Secretariat of the AdM Commonwealth of Municipalities.
