Comparison of the two versions of Lake Karla watershed hydro-economic model's characteristics
| Version 1 . | Version 2 . |
|---|---|
| Incomplete data and recordings (hydrological and economic). As a result, the scope was a preliminary understanding of the system | Complete and reliable official data per farm (Greek Agency of Payments and Control for Community Aid 2014). The aim was to prepare for a complete monitoring and implementation of the economic objectives of the WFD |
| Desirable outputs: water balance, irrigation water cost, farmers' utility, irrigation water value, management scenarios | Desirable outputs: water balance, net profits, deficit water value, overexploitation index, water quality, demand management plan |
| 4 main crops were used, because of limited data. Statistic databases and satellite methods were used | 11 crops were used, as they were classified from the official per-farm data |
| The watershed is divided into 10 (min) and 19 (max) irrigation zones (for baseline and future scenario respectively) This division offered higher precision, spatial integration of the results and ‘covered’ the weakness of the limited data that were used for the analysis (Figure 3(a)) | The watershed is divided into 3 zones depending on the supply source (water bodies), as it is convenient and useful for the simulation of the quantitative and qualitative degradation of each water body of the watershed (Figure 3(b)) |
