Science-based research and practical construction quality evaluation criteria predict groundwater resources, serve warning, forecasting groundwater resources.

Currently forecasting water resources in general and water resource forecasts underground particular importance to the cause of socio-economic development, national security, and particularly in the work of prevention initiative natural disasters and mitigate the damage caused by water. In conditions of growing social demand requires monitoring data and forecast information on developments increasing water resources, not only rich in terms of content but also the accuracy of the information forecast. Therefore, the evaluation of the quality of forecasts of underground water resources is a very necessary and increasingly by the management bodies of water resources and water users more attention.

From the fact that the theme: "Research scientific basis and practical construction quality evaluation criteria predict groundwater resources, serve warning and forecast of groundwater resources" are proposed. the results obtained from this study will build quality evaluation criteria predict groundwater resources serve warning, forecasting groundwater resources North delta areas and the draft guide rated forecast quality underground water resources land North delta areas, ensure objective evaluation of ease of use, in accordance with conditions of warning, forecasting groundwater resources today.

The evaluation of the quality of forecasts resource developments of groundwater is one of the basic criteria for evaluating the work of the Center Warning and Forecast of Water Resources Center of Planning and Resource Survey national water, simultaneously, through quality forecast of underground water resources, which can be driven research and improve the quality of forecasts a place to know the details of the product strength present. However, the issue of assessing the quality of forecasts evolutions of groundwater resources is a very complex issue because in fact, there is no one method or normative ratings cover all purposes assessing the quality of forecasts. Many experts believe that water resources quality assessment forecasts difficult and complicated, much less to make the forecasts. The difficulties presented in the following main points:

- The complexity of water resource developments, factors and water resources and forecast related to space, time and their intensity;

- The nature of the notification, warning, forecasting (monthly newsletter, quarterly newsletters, bulletins years, ...);

- The methods and evaluation criteria are not unique;

- The convention of limited magnitude, space and time are not uniform;

- The process of socio-economic development and science and technology makes the observation and forecasting of water resources to change, society's requirements, the user's changes. The changes are accompanied by changes in terminology, on the convention in space, time and the nature of newsletters ...

According to experts on water resources, there are 3 most important reasons need to assess the quality of forecasts of underground water resources are:

1. To monitor the quality of forecasts: view the monitoring data and accurate forecasts to what extent and with increasing accuracy levels better?

2. To improve the quality of forecasts of underground water resources: because we must first find out what the forecast wrong, wrong how they can improve forecasting technology.

3. To compare the forecast quality of the various forecasting systems.

Thus, the theme: "Research scientific basis and practical construction quality evaluation criteria predict groundwater resources, serve warning and forecast of groundwater resources" focused studies general overview of the evaluation of the quality of forecasts of water resources in the world and Vietnam; To study and formulate criteria for evaluating the quality of forecasts of underground water resources Month Northern Plain region; Research proposed draft guidelines for assessing the quality of the forecasts of underground water resources Month Northern Plain region.
