I am trying to assess how water resources evolved after increasing drought due to climate change.
Francisco, creo que lo mejor es que consultes a Sergio Vicente ([email protected]), uno de los mejores especialistas en sequías y que además trabaja en hidrología. Es probable que en alguna de sus publicaciones encuentres la información que buscas, pero mejor si contactas con él.
Un abrazo.
I think your question is somewhat complicated if one can consider that the evolution of water resource does not only depends on the occurrence of a drought, which is one of the extreme event of global climate change, but factors such as legislation on water use and water management, population growth, water contamination, forest destruction, soil erosion, among others, must be taking into account to assess the impact of drought on the referred issue. It might be helpful to revise the IPCC experts approach for scenarios construction.
Dr.Francisco,I could not understand whether you are asking a question or telling the scientific community that you know some method to assess the impact of drought on evolution of water resources.As opined by Casareo your question is a complicated one.Evolution is a very long-time and slow process.Whether you want to know the shorter or lager scale?To my knowledge there is no method for the study.But you can take long-term data of drought index along with volume some specific water resource like volume of water of some water body to get some type of relation.
In my opinion, the key issue is equipping the research laboratory with precise devices for measuring rainfall, air humidity and soil moisture at specific measurement depths. In addition, an important issue is the appropriately long period of measurements to make the results of research independent from seasonal changes of the seasons, cyclically changing periods of drought and rainy season, etc. Increasing drought has a direct impact on the reduction of surface, subcutaneous and groundwater resources. However, the impact of drought on deep water resources depends on the passage of time, depth and type of deep water resources and the type of rocks between which these water resources are located. Deeper deep water resources, such as the Oligocene ones, can be fully independent of changes in weather and climate on the Earth's surface. Therefore, another issue is to determine what kind of water the local community uses, and therefore it is important to determine to what depth the water resources will be tested.
