About maps

Maps are created according to the questionnaires fulfilled by reporters once a week, always at the same location. Reporting is a part of the activities within DriDanube project.

Map 1. presents estimated drought impact on main crop yield, fruits, viticulture, olives and forest in previous week in Croatia. According to the fulfilled questionnaires for each county the mean is calculated and presented on the map according to the following symbology:

counties with no report
counties with no drought impact
counties with drought occurrence with/or impact on crop yield
counties where drought occurrence is likely to reduce crop yield
counties where drought occurrence significantly reduces crop yield
counties where drought occurrence substantially reduces crop yield (the worst scenario)

Pictograms at each county have the following meaning:

forest
fruit trees
grapevine
barley, wheat and rape
sugar beet and potatoes
corn
severity of drought impact is presented by different size

Map 2. presents water balance for the last three months. Each dot on the map belongs to the location for which the questionnaire is fulfilled. The color of dots presents the severity of drought in the following way:

extremely humid - precipitation excess with negative impact
very humid - with noticeable negative impact
normal state / moderate humid period without negative impact
rather dry period without noticeable impact
severe drought - precipitation deficit with noticeable negative impact
extreme drought - precipitation deficit/intense drought with significant impact

Map 3. presents state of soil moisture in the layer 20 cm from the surface at the location for which the questionnaire is fulfilled. The color of dots presents the dryness of soil in the following way:

the soil is dry to touch and non-moldable
the soil is rather dry to touch with loose consistence
the soil is slightly moist, moldable with low cohesion
the soil is moist, well moldable
the soil is very wet, sticks to fingers
out of classification scale

Note: Week number refers to the week when the map was created.
