ACTION 3

Development of basic modelling procedures to be applied to the GIS 

Action 3.1

Soil Hydrological Modelling

This action aims to test and evaluate hydrological models for further implementation in the SDSS. These modelling procedures are termed "basic" just because their application and outputs will be utilised as base data to operate applied modelling procedures planned in the next actions 4.

Progress

After a first test phase aiming to verify the most reliable models (in terms of applicability and performing) in the area of Valle Telesina (using soil and climate data from our databases), the SWAP model was chosen to describe the soil water balance processes. In particular, the ability of the model to describe the soil water balance was evaluated on two important agricultural systems of Valle Telesina: olive culture and viticulture. The tests have provided good results both in terms of soil water content predictions and on derived functional properties such as the crop water stress index. This index is now mapped and is part of the DSS database;
SWAP model was also applied to evaluate olive crop adaptability to climate change over the study area. This modelling application was carried out in collaboration with the national research project AGROSCENARI (funded by MIIPAF) and presented to the General Assembly (2011) of the European Geosciences Union with the contribution titled "Assessing the adaptive capacity of some olive cultivars to future climate" (Riccardi et al, 2011).  SWAP model was used to solve the soil water balance and to derive again an index of water stress distributed over the area. The latter, combined with the crop yield response function to water stress, was used to identify areas suited, or otherwise, to olive cultivation for eleven different olive cultivars. SWAP coupled with another model was also applied so as to derive an index of vine stress usable for management purposes. Currently experts are working on the recompilation of the SWAP code in the UNIX language starting from the original FORTRAN language, in order to allow the use of the simulation model directly within the WB-SDSS. Moreover, an internal test of its performance has already been made, comparing its outputs with those obtained from the original program applying the same input data.

The action is now concluded, the activities planned have been concluded. The hydrological model SWAP was recompiled and now it is part of the dynamical section of the DSS. As planned, the model has been applied in the production of several thematic maps (mainly utilised for the viticultural tool) and indexes. See action 4.1 and 4.2 for details about the applicative use that we are doing of it, now that it is integrated in the spatial DSS.

Action 3.2

Microtopography classification

This action aims to realize a segmentation of a landscape in geomorphological classes, starting from the analysis of a DEM available.

Progress

The segmented landscape (i.e. concavity, convexity, slopes, etc.) is a likely model of landform spatial distribution and, in turn, it is used to increase understanding of the spatial distribution of other physical landscape parameters. The segmented landscape will be used as auxiliary data for mapping the spatial distribution of soil properties such as sand and clay content, organic matter content, etc. First landform classification was carried out starting from the analysis of a Digital Elevation Model of the Valle Telesina at 20 m resolution. The elaborations were based on a Fuzzy Landform classification approach.
The action is now concluded. If needed, the landform classification already performed could be ameliorated using as primary data the new LiDAR DEM (very high resolution) acquired within the project balance.

Action 3.3

Potential solar radiation microzoning

The action is focused on the production of a land classification according to areas with different potential solar radiation. These data come from the DEM elaboration.

Progress

Maps of potential solar radiation are very useful for agriculture planning purposes, especially for viticulture. Two continuous maps of annual solar radiation in the Valle Telesina area were produced. The maps were respectively based on a 20x20 and 5x5 m DEM resolution. These maps were uploaded in the SID and are now implemented in a tool of the SDSS designed for users interested in environmental information about their terroir (see action 4.2).
Subsequently, four more maps were produced (as planned) derived from high resolution DEM elaboration whose utilization is planned for viticultural zoning. These maps represent the potential radiation over the study area of Valle Telesina corresponding to time periods defined in accordance with vineyard phenology. The action is concluded.
