| Zusammenfassung |
| Agro-areas of Arroyos Menores (La Colacha) west and south of Río
Cuarto (Prov. of Córdoba, Argentina) basins are very fertile but have
high soil loses. Extreme rain events, inundations and other severe erosions
forming gullies demand urgently actions in this area to avoid soil
degradation and erosion supporting good levels of agro production. The authors
first improved hydrologic data on La Colacha, evaluated the systems of
soil uses and actions that could be recommended considering the relevant
aspects of the study area and applied decision support systems (DSS)
with mathematic tools for planning of defences and uses of soils in these
areas. These were conducted here using multi-criteria models, in multi-criteria decision making (MCDM); first of discrete MCDM to
chose among global types of use of soils, and then of continuous MCDM to evaluate and optimize combined actions, including repartition of
soil use and the necessary levels of works for soil conservation and for hydraulic management to conserve against erosion these basins.
Relatively global solutions for La Colacha area have been defined and were
optimised by Linear Programming in Goal Programming forms that are
presented as Weighted or Lexicographic Goal Programming and as Compromise
Programming. The decision methods used are described, indicating algorithms
used, and examples for some representative scenarios on La Colacha area are given. |
