## 3 Results and Discussion  
The survey sample for evaluating the Canal de Castilla's importance consists of a diverse cross section of 100 individuals from Alar del Rey, a small population of 829 according to the National Statistics Institute 2023 data. This represents a substantial proportion, suggesting a robust basis for the conclusions drawn [26]. Gender distribution skews heavily female, with women constituting 68% of respondents, potentially reflecting greater engagement or availability for surveys in this demographic. The equal split among residents indicates that the survey captures perspectives from both permanent inhabitants and those who reside in Alar del Rey seasonally or occasionally. The educational level varies, with a significant share having completed baccalaureate or vocational training (35%), followed by those with university degrees (27%), which suggests a well-educated sample that may provide informed opinions on the canal's restoration and sustainability efforts. Age diversity is notable, with respondents spread across life stages: 25% are in their fifties, highlighting mature insights, while the younger (18-29) and forties (40-49) cohorts represent 20% and 16%, respectively, infusing youthful perspectives and midlife practicalities into the feedback. The inclusion of seniors (8%) and the elderly (14%) adds depth, indicating intergenerational concern for the canal's future. The results are shown in Figure 3. Displayed here is the demographic profile of respondents who participated in the survey centered around the Canal de Castilla's restoration and sustainability proposals. The pie charts meticulously detail the gender balance, residency status, educational attainment, and age range of the surveyed individuals. This visualization serves to illustrate the breadth of community engagement in this study, with particular attention to the blend of local and nonpermanent residents, the array of educational backgrounds contributing to the depth of feedback, and the wide span of ages reflecting the multigenerational investment in the canal's future. Such demographic breadth strengthens the survey's credibility, ensuring that the forthcoming results and proposed interventions for the canal reflect wide-ranging community needs and expectations. Figure 3: Demographic distribution of survey respondents for Canal de Castilla study. The first domain surveyed was the importance, benefit, and positive impact of urban development initiatives on the Canal de Castilla, focusing on restoration and modernization efforts. Key terms used in the survey questions to elicit precise responses included \"restoration impact\", \"architectural integration\", \"heritage conservation\", \"infrastructure improvement\", and \"urban revitalization\". In analyzing the results, we find a dominant majority of 59% perceived the impact of urban development on the Canal de Castilla as \"High\", while 28% considered it \"Very High\". This accounts for 87% of respondents affirming significant value in building and urban development initiatives related to the canal. A smaller segment, 10%, rated the impact as \"Medium\", with only 3% viewing it as \"Low\". Notably, no respondents felt that the impact was \"Very Low\". These findings, visualized in Figure 4, where the darkest shades represent the most positive impact, suggest a strong community consensus on the high importance of building-related initiatives for the Canal de Castilla. The data reflect broad support for urban planning measures aimed at enhancing the canal's structure and function, indicating a favorable public opinion towards investing in the canal's architectural and infrastructural renewal. The second area of focus in the survey was the role of research in enhancing the Canal de Castilla's value and its future prospects. Keywords in the survey revolved around \"historical research\", \"sustainable engineering\", \"technological innovation\", and \"ecological impact studies\", aiming to quantify the perceived benefits of research on the canal's enhancement.
