## 7 Conclusions
It is one of the most open valleys in Bizkaia. It is bordered by mountains of low altitude without exceeding 360 m in height. The lands through which the courses of this basin run are mainly made up of marl and limestone, crossing the main river alluvial lands from the middle stretch to the mouth.The shape can resemble a rectangular figure of proportions 1.5 to 1 with respect to length and width. * Artibai, Bizkaia, Spain. The Artibai river is about 20 km long, and extends in a S-NE direction. Its origin are two groups of streams from mountains between 1029 m 793 m altitude. The geological substratum of the basin is predominantly limestone at the head and later sandstone and clay. The fluvial bed is stony with a predominance of blocks or boulders both in the streams and in the main channel. The shape can resemble a rectangular figure of proportions 2 to 1 with respect to length and width. * San Antonio river sub-basin, station Loop 410, Texas, USA. It is a sub-urban basin, having an average slope of 0.2%, and a climate that alternates between dry and humid, summers are hot and winters vary from mild to cold; the average annual rainfall is 738 mm. It can resemble a rectangular shape of proportions 2 to 1 in relation to length and width. * San Antonio river basin, station Goliad, Texas, USA. The morphometry of the San Antonio River basin includes the contribution to the Goliad station. The basin has been considered regional as a single unit of drainage area, most of its surface being permeable. It has slopes from 0.2% to 3%, has an elongated shape from northwest to southeast, the climate is varied, alternating between humid and predominantly dry. Being an extensive drainage area of the regional type, the area of incidence of storms has been distributed spatially. The shape is very elongated with a ratio of 5 to 1 with respect to the width. * Juquia river basin, station 4F-018R, Ribeira Do Iguape, Sao Pablo, Brasil: We have considered the sub-basin of the Juquia River in the hydrometeorological station 4F-018R, which includes a drainage area equal to 4360.0 km\({}^{2}\), code 81679000, basin of the Ribeira Do Iguape River, Sao Pablo, Southeast Atlantic Hydrographic Region, Brazil. The topography is mountainous with the characteristics of a somewhat flowing and turbulent river. The region has a hot tropical climate, with high temperatures in summer. The high rainy season occurs in winter with mild temperatures. Formed by two sub-basins, its shape is elongated at the headwaters and widens at the exit. * Bermejo river upper basin, station Balapuca, Argentina-Bolivia. The basin is located in the north of Argentina, province of Salta, sharing a part with Bolivia; the sub-basin belongs to the Bermejo river basin. It has the mountainous ecosystem of the Andes Mountains with an average slope of 35%. The hydrological regime of the rivers is purely pluvial with a well-defined seasonal variety, characterized by a period of important flows in the rainy season. The shape of the basin can be assimilated to a square shape of relation 1 to 1 with respect to the length and width. The basins are depicted in Figure A1.
